Barrel mixer

Abstract

There is disclosed a barrel mixer ( 11 ) comprising a support ( 12 ) for a rotary mixer barrel ( 13 ), including a tipping arrangement ( 14 ) for said barrel ( 13 ) limiting tipping between a mixing position in which the barrel ( 13 ) is angled so as to retain its contents and a tipping position in which the barrel ( 13 ) is angled so that its contents are poured out, a motor ( 15 ) and transmission ( 16 ) mounted on said support ( 12 ) for rotating the barrel including step-down gearing between the motor ( 15 ) and the barrel ( 13 ), the motor ( 15 ) and gearing ( 33 ) tipping with the barrel ( 13 ), the motor shaft ( 15 b ) being, at an intermediate position between mixing and tipping positions of the barrel ( 13 ), vertical, and the motor ( 15 ) being of a type having a mounting plate ( 31 ) surrounding the motor shaft ( 15 b ).

1. A barrel mixer comprising:
 a support means comprising a stand and a wheeled trolley, the stand having a pintle bearing provided to receive the wheeled trolley;  
 a rotary mixer barrel mounted on the wheeled trolley;  
 a motor mounted on the wheeled trolley and having an output shaft;  
 a transmission mounted on the wheeled trolley, the transmission receiving the output from the motor and including step-down gearing, an output from the transmission rotating the rotary mixer barrel;  
 a tipping arrangement, the tipping arrangement comprising a tipping limiter means, the tipping limiter means comprising first and second tipping limiting stops mounted on the wheeled trolley, and the tipping arrangement permitting the wheeled trolley to be tipped on the pintle bearing between a first position, in which the wheeled trolley engages the first tipping limiting stop, and a second position, in which the wheeled trolley engages the second tipping limiting stop; and  
 wherein the first tipping limiting stop defines a mixing position, wherein when the wheeled trolley is in the first position the barrel is angled to retain its contents, and the second limiting stop defines a pouring position, wherein when the wheeled trolley is in the second position the barrel is angled so that its contents are poured out, and the first and second limiting stops limit movement of the barrel between the mixing and the pouring positions.  
 
   
   
     2. A barrel mixer according to  claim 1 , wherein the wheeled trolley comprises a frame, the barrel being supported on one side of the frame and the motor and the transmission being supported on the opposite side of the frame. 
   
   
     3. A barrel mixer according to  claim 2 , wherein the wheeled trolley further comprises a frame base and wheels mounted on the frame base, the frame base being on the same side of the frame as the barrel. 
   
   
     4. A barrel mixer according to  claim 3 , wherein the frame further comprises handle means projecting from the frame at the opposite end thereof to the frame base and on the same side of the frame as the motor and transmission. 
   
   
     5. A barrel mixer according to  claim 1 , wherein the barrel is demountable from the wheeled trolley and the support means breaks down to fit inside the barrel for storage or transportation. 
   
   
     6. A barrel mixer according to  claim 1 , wherein the wheeled trolley is supported by the stand. 
   
   
     7. A barrel mixer according to  claim 1 , wherein the wheeled trolley is demountable from the support means. 
   
   
     8. A barrel mixer according to  claim 7 , and the support means breaks down to fit inside the barrel for storage or transportation.
